A fixing ring 19 matching the pressure rod 11 is provided on the top of the telescopic rod 10, and a screw hole 20 is provided inside the fixing ring 19 and the pressure rod 11. The fixing ring 19 and the pressure rod 11 are connected to the screw hole 20 by bolts 21 in a movable connection, and an elastic pad 22 is provided on the outside of the pressure rod 11.
[0026] Reference Figure 3 , Figure 4 The leg-pressing mechanism includes a snap ring 23, an arc-shaped clamping plate 24, a threaded rod 25, a leg-pressing seat 26, an arc-shaped support plate 27, an adjustment groove 28, a threaded post 29, and a sponge pad 30. The snap ring 23 is sleeved on the outside of the pressing rod 11, and the arc-shaped clamping plate 24 is provided at the lower part of the snap ring 23. The arc-shaped clamping plate 24 is rotated and clamped by the threaded rod 25. The leg-pressing seat 26 is provided at the top of the snap ring 23, and the arc-shaped support plate 27 is provided on both sides of the leg-pressing seat 26. The adjustment groove 28 is provided below the arc-shaped support plate 27 inside the leg-pressing seat 26, and the threaded post 29 is provided inside the adjustment groove 28. The sponge pad 30 is provided at the top of the arc-shaped support plate 27 to form the leg-pressing structure.
[0027] In practical implementation, when installing an adjustable dance leg-pressing training device, firstly, because there are mounting holes 4 on both sides of the upright plate 1 and inside the fixed plate 3, it is easy to fix the upright plate 1 and the fixed plate 3 to the wall and the ground respectively. Then, by manually turning the knob 12, the lead screw 6 rotates accordingly, so that the slider 7 moves up and down inside the slide groove 5, thereby realizing the height adjustment of the support frame 8 and the pressure rod 11 to meet the needs of dancers with different heights, leg lengths and flexibility. Next, the locking ring 23 is put into the outside of the pressure rod 11, and the threaded rod 25 is manually turned, so that the arc-shaped clamp 24 moves up and down, thereby making the locking ring 23 secure to the outside of the pressure rod 11. According to the different sizes of the user's feet, by manually turning the threaded column 29, the arc-shaped support plate 27 can be moved, thereby making the arc-shaped support plate 27 push the sponge pad 30 for adjustment. Through the above operations, the user can easily adjust to a suitable position to ensure correct posture, comfort and naturalness during training.
[0028] Reference Figure 2 , Figure 5 The telescopic sleeve 9 has a threaded hole 13 at its bottom and a threaded cover plate 14 matching the threaded hole 13 inside the telescopic sleeve 9.

The top of the locking block 18 is connected to the telescopic rod 10.
[0029] In practice, firstly, by rotating the threaded cover plate 14, it can be removed from the bottom of the telescopic sleeve 9, allowing the damping rod 15 and spring 16 to be replaced. Conversely, they can be installed. When the dancer stretches their legs, the telescopic rod 10 will receive downward pressure, which will then push the locking block 18 to move up and down inside the slide 17. At the same time, the damping rod 15 and spring 16 will generate upward tension. The dancer can feel the gradually increasing force feedback during the leg stretching process. Through the above operation, it helps to enhance the strength and endurance of the dancer's leg muscles, and also improves the body's coordination and balance.
[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
